If no electronics module is available onside, the module can be ordered for the VEGA agency serving you.Ordering and exchange are possible with or without sensor serialnumber. The electronics module with serial number includes order-specific data such as factory setting, seal material etc. These are notincluded in the electronics module without serial number.The serial number is stated on the type label of VEGABAR 65 or on thedelivery note.8.5 Software updateThe following components are required to update the sensor software:l SensorVEGABAR 65 • Profibus PA 498 Maintenance and fault rectification28253-EN-081209
